Default Re: Evaluating 305E engine noise
So I made some progress today; confirmed spark to all six cylinders, then pulled the valve covers. lo and behold, cylinders #1, #3 and #6 all had bent intake valve pushrods! The seller said the vehicle had sat for years, and I presume this is the result of stuck lifters? I turned the engine by hand and could see all three push rods move up and down; am I correct this means the lifters are unstuck now? Plan is to replace with a new set of push rods, then do a valve adjustment. Feels nice to move forward!
